So in my house I have a room temperature at around 65F. I'm using a 34QT Tub with a Flexwatt heat pad as well as a Zilla 1000 Watt Temperature Controller as my thermostat. I am able to get my hot side up to between 88F to 92F and maintain it no problem but my cold side sits around 74F? I realize it should be in the lower 80's so? I am able to buy another heat pad and thermostat if I NEED to. I will need to buy another thermostat because if you don't already know it can only work on one source since there's only one probe, not two. Or anyways should I not even worry about buying another set-up and just leave it at around 74F? I'm using Aspen bedding so It could get even warmer by burrowing but whatever. Want to know what you guys think Thanks.
